Shakira and Rihanna know a couple of things about falling in and out of love after years of making songs about the subject. They're still making the same mistakes, though. The hip-shaker and twerker team up to harp about their issue on their new collaboration, 'Can't Remember to Forget You.'

A ska-flavored guitar drives the verses as Shakira and Rihanna lament on their inability to forget a former lover. They try to, but it's not like they want to according to the hook: "But when you look at me, the only memory, is us kissing in the moonlight."

Rihanna is slightly more explicit in her shortcomings as she sings, "Fall off the train / Land in his bed / Repeat yesterday's mistakes." The guitars start to climax as the singers reveal why it's best to forget the lover, lest they face legal issues: "I rob and I kill to keep him with me."

'Can't Remember to Forget You' will appear on Shakira's next album -- the follow-up to 2010's 'Sale el Sol' will drop on March 25. The Colombian entertainer also shared that she finished shooting a music video for the song, which will also star Rihanna.
